"Today I played very good, one of the best matches on my career in the
Australian Open," Ferrer said. "I'm very happy with my game. The result, it
was in three sets, but the game, it was very, very difficult to beat
Nishikori."

The No. 10 seed Almagro advanced when No. 8 Janko Tipsaveric retired with a
foot injury while Almagro was holding a 6-2, 5-1 lead. Almagro had lost in the
fourth round in each of his last three years.

Ferrer and Almagro will meet in the quarterfinals in an all Spaniard affair.

Also on Sunday, top-seeded Novak Djokovic, the two-time defending champion,
will square off against No. 15 Stanislas Wawrinka, while fifth-seeded Tomas
Berdych is currently in action against Kevin Anderson.
